Of course, given the late night hours we’re talking about, we’ll likely see the decline since the 4 AM peak continue as more normal people come on line. I’ve been using it since last night and so far, I like it. The bookmark interface probably needs a little work, but that’s my only complaint so far. The added browser window space is very nice.
UPDATE: I should point out that it seems to have trouble with AJAX modal popups. If you don’t know what that means, don’t worry about it.
